M-25 Grade concrete is a type of concrete with a compressive strength of 25 megapascals (MPa).

• M-25 Grade concrete is commonly used in construction projects.

• The ratio of M-25 Grade concrete is 1:1:2, which means 1 part cement, 1 part fine aggregate (sand), and 2 parts coarse aggregate (stone).

• The mix proportion of M-25 Grade concrete is designed to achieve a desired strength and durability for the specific application.

The number of bricks required in 1 cubic meter depends on the size of the bricks and the thickness of the mortar joints.

• The size of the bricks and the thickness of the mortar joints determine the number of bricks needed.

• Standard brick sizes are commonly used in construction.

• For example, if the size of the brick is 200mm x 100mm x 75mm and the thickness of the mortar joint is 10mm, the calculation would be as follows:

Method of estimation refers to the process of calculating the approximate cost of a project or task.

• Estimation can be done using various methods such as approximate quantities method, detailed estimate method, and unit rate method.

• Factors such as labor cost, material cost, equipment cost, and overheads are taken into consideration while estimating.

• Estimation can be done manually or using software such as AutoCAD, Excel...read more

The ratio of concrete refers to the proportion of cement, sand, and aggregate used in the mixture.

• The most common ratio of concrete is 1:2:3, which means one part cement, two parts sand, and three parts aggregate.

• Other ratios include 1:1.5:3 and 1:3:6, depending on the strength and durability required for the project.

• The ratio of concrete can also be adjusted based on the type of project, climate conditions, and availa...read more
